The description page loads fine for me in Iceweasel 10.0.0.2 on Debian unstable. (Iceweasel is Debian's fork of Firefox.)
Perhaps you have Javascript blocked or something like that?
Confirming that it also works in Iceweasel-libre 18.0.1-3 on Parabola. (Iceweasel-libre is Parabola's fork of Debian's fork of Firefox)
For me the link redirects to the front page of the Chrome Web Store, so I guess that's what's happening to you, too. But by entering "secure shell" in the search box I can view the screenshots, description and reviews of the app being discussed. Firefox 18 on Linux.
The link works perfectly in firefox here, can see the screenshots, descriptions, etc?
